moisture. A room temperature of 25°C ±15°C is recommend-
ed.

damaged by mechanical or any other in fl uences.

Ball valves that weigh more than approx. 10 kg should be
stored on a pallet (or supported similarly).

tion. They must be stored in the position in which they were
delivered. The actuating device must not be actuated.
